Orbital Sciences Corporation’s Cygnus spacecraft was scheduled to rendezvous with the International Space Station this past weekend in a resupply mission. However, the date has been postponed until Saturday at the earliest since the spacecraft didn’t past the tests it needed to before docking. A data format mismatch hindered the initial green light, which is now said to be fixed. But the delay left Cygnus standing in line behind Expedition 37/38’s three new residents to the ISS, who will arrive Wednesday night. If this resupply is successful, Orbital has eight more planned.
